Question about Acer Aspire 5100 Notebook
In a lot of laptops 3 beeps on post check during boot up means an issue with either internal memory or the memory sticks in the laptop. If you know how to take out the memory sticks that is the first thing to check. To do so locate the memory sticks. Before taking them out make sure you are in a as static free environment as you can be. Idealy you can use a wrist ground strap to ground yourself to the laptop to eliminate any possible static built up in your body from discharging into the memory stick and possibly damaging it but I have changed many and never used one an never had one fail.
I try to do it in a non carpeted room. Remove the battery and make sure it is of course unplugged. Also after unplugging and removing the battery I hit the power button so if there is any stored energy inside the motherboard it will discharge in a way. I have a sager with such huge capacitors in it it actually momentarily lights up the power on led when I do this so yes there can be trapped energy so I reccomend this step. There are two tabs on either side of the memory stick that you carefully push outward and this allows the stick to release (pop up) evenly pull it out of the socket. Using a clean eraser lightly rub the gold contacts to clean them if they seem dirty. Shouldnt be on a laptop that new but never know. Make sure no eraser residue is on the stick and put it back in the slot and push down till locks back into tabs.
Try booting up the laptop if this doesn't work try using only one of the two memory sticks at a time to test if only one of the two is bad. If this does not work than if it is a internal memory problem you will have to have it serviced.
If this does not solve it then you could try removing one at a time and booting after removing the wireless card, cd/dvd (optical drive), hard drive, modem or memory card reader board ect. ect. but some of these may take a bit more experience to remove for some.
I am only self taught at laptop repair but I am no rookie to electronics either so hope this helps.
